'- YARN-GUIDE.

- Specification of Letters Patent.

Patented Jan. 21, 1913.

T5 all whom it may concern l Be 'it known that I, CLAEs .RYDEN, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Yarn-Guides, of which the following is a specification.

My invention relates to improvements in I threador yarn-guides for use on textile machinery such as winding machines, spinning frames and other like apparatus.

The object of my improvement is to provide a-self-threading yarn-guide which can be threaded with greater ease and convenience than the usual igtail or spiral guiding eye and which is adapted to prevent the thread or yarn from whipping or juniping out as it draws rapidly through the eye.

A further object of my invention is to provide a bearing surface for-the thread which will resist wear and prevent the cutting of a groove or channel from the abrasive action of materials such as silk, linen or other hard twisted-threads.

The invention isfully described in the following specification, illustrated by the accompanying drawings, in which Figure 1 is a perspective view of my improved guide illustrating the method of drawing the thread into its opening or eye; Fig. 2, an enlarged plan view of the same; Fig. 3, a side elevation; F 4, an end elevation, part sectional on the line AA of Fig. 2, and showing the manner in which the thread draws into the eye and also the position it assumes when loading through the eye; Fig. 5, an end view showing a modification in the construction of the invention; Fig; 6, a side view of the same; and Fig. 7, a

plan view.

My improved guide might be constructed of steel, brass or any-suitable material. but

I prefer to make it with the main portion of In Fig. 1 the arm e is shown in a osition which would adapt it to be applie to an unwinding device such'as described in my United States Patent, No. .9 81,950, dated January 17th, 1911, to be used in place of the arm which controls the rotation of the skein-holder through the tension of the yarn drawing through the guide at its end. It

will be obvious, however, that the exact posi' tion of the guide and its arrangement in connection with the machine is not essential tothe novelty of the invention.

The member I), as before stated, is referably constructed .of'porcelainfa'nd is ormed with a longitudinal hole f adapted to re ceive the screw 9 which secures it to the cross-bar c. The threadway or-eye d in the member .I) is preferably circular in shape with acontracted openln Fig, 3. On one side oft is openin is an '7z. at its top, see

abutment k and on the other a curve hornlike prong Z. 1 ThecroSs-bar c is slotted at m and bridges ,the opening with the abutment A; and prong Zextending up into the slot, see Figs. 2 and 3. It is to be noted, however, that while the abutment 70 extends some distance through the slotm and reaches up' beyond the cross-bar, the prong Z does not project clear through the slot in the bar. right-angles in the extension 11, which abuts the end of the member I), the latter being held in place by the screw 9. Preferably a washer 0 of fiber, leather, or some siinilar yielding material is interposed between the head of the screw and the end of the member b so t-hatthe latter will not be chipped or cracked screw.

ln Figs. 5, 6 and 7 a modification of the Theend 'of thecross-bar c is bent at the clamping pressure of the above described structure is shown in which the member I) is secured to an arm 7) ahdthd cross-bar 1' is made in a separate piee. The arm p here shown is a'portion of the stopping lever-used on a. well known form of winding machine. hitt is not illustrated in detail as its relation to the machine-is not essential to the present invention. In this arrangcn'ient the screw 1 extends first through the arm 7 then through the Iuemher 7; with its threaded end screwed into the right-angled extension 2 of'the cross-bar v. .-\s in tho-previously described arrangement the cros -luirfhridgus the opening 72 of the member I) and the sides of the slot m straddle the abutment k and prong Z. The posite extremity of the cross-bar is tapere ofl to a point and curled up in the crook a which serves'as a guide for the thread in drawing it int'othe eye d as later explained. The method'of operation of the device is as follows; To thread the guide the yarn 3 is drawn up againstthe underside of the cross-bar c and pulled toward,themember b, asillustrated in Fig. 1. The curved side of the prong Z causes the loop 00 of the yarn to vride up through the slot of the cross-bar a and by drawing the forward end of the yarn yarn will seat itself in the eyea, taking the to preventv the yarn from whipping out ofdodge it from the guide whi position illustrated by dash'linesin Fig. 4. The purpose of the abutment la is to guide the 'yarn down into the eye d.when it is drawn past the end of the prong] and also the eye. After the yarn is in position leading through the eye (1 it is impossible to dise its endsare held taut. .Should it whip up against the cross-bar c, as illustrated by dotted lines in Fig. 4, it'is restrained therebyfrom throwing out through the opening h. The only possible manner in which the yarn can be removed from the guide without breaking it is to loop it up. over the prong 'Z and under. ordinary conditions when the yarn is drawn taut under tension this could not be aocom plished.

It will be seen that my invention provides a guide which can be threaded with extreme quickness and facility and when the yarnis in its proper position in the guidingeyeit cannot whip or jumpout or be otherwise accidentally dislodged. With the usual form of pigtail or helical guide wire it is necessary for the operator to give the yarn a turn under and around the spirali'n thread- -ing-'it through the eye. This not only requires more time and care, but unless the operator is extremelycareful a bight -is liable to be formed around the wire' and when the yarn is pulled taut it 'will break.

I n my improved guide herein" described it is practically impossible to form a loop or bigh't in the-yarn in threadingit into the guide, and the operation is so extremely simple that there 15 no chance for a misap-- pliance. Furthermore, the invention provides against wear in-the guide-eye and therefore the device is much more durable. ,Itwill be understood that my invention is not limited in exact form or dimension to.

the embodiments herein illustrated.-. Various modifications might be made in the structure and arrangement of the parts without departing from the spirit or scope of the invention.
